Abstract:
A first liquefied hydrocarbon stream is provided from a first source and a second liquefied hydrocarbon stream is provided from a second source. The second liquefied hydrocarbon stream has been liquefied by cooling solely against a first cooled nitrogen-based stream. The first and second liquefied hydrocarbon streams are gasified to produce a gasified hydrocarbon stream, thereby cooling a gaseous nitrogen-based stream against the gasifying first and second liquefied hydrocarbon streams to provide a second cooled nitrogen-based stream.
